UFC 91 takes place Nov. 15 at the MGM Grand Garden Arena in Las Vegas. It airs on pay per view.

The NSAC's year-round testing was implemented earlier this year. MMA fighters are subject to drug testing at any time -- for just about any reason -- throughout the year, regardless of whether or not the fighter is scheduled for an upcoming event. However, the testing is usually reserved for scheduled fighters.

For more on the NSAC's new procedures, check out our interview with Kizer that followed the commission's official announcement.

I don't know how many fans realize how big this is or the potential impact but if HGH and others are as rampant as a few fighters have came out and stated they are this could change the balance of fighters in the UFC, Im just glad Randy came back clean! Now all the people that assumed Couture was juicing can shut it.

I think people are slightly confused on the topic of "random drug testing" anyway, though... I think this is great. I've always said that people would be insane to believe that at least 70% of fighters aren't on or haven't ever been on steroids throughout their lives. This moves MMA one step closer to being legitimized on a grand scale imo. So to NSAC which is doing a much better job than CSAC
